Custom Tag Color

An Obsidian plugin that lets you assign custom colors to tags using regular expression (regex) patterns. Create flexible rules that automatically color tags based on their names, prefixes, numbering schemes, dates, times, emojis, and more.

Features

  • 🎨 Assign custom color to tags.
  • 🔍 Match tags using powerful regular expressions.
  • 📋 First matching rule takes priority.
  • 🌈 Automatically derives complementary background colors.
  • ➕ Add, edit, and remove rules from an intuitive settings panel.
  • ♻️ Reset all rules to the default example configuration.
  • 📱 Works on both desktop and mobile versions of Obsidian.

Examples

Goal Regex Pattern
Match exactly #important ^important$
Match dates like #21/06/2026 ^\d{2}/\d{2}/\d{4}$
Match times like #09:30 ^\d{2}:\d{2}$
Match times like #09-30 ^\d{2}-\d{2}$
Match #war1, #war25, #article10 ^(war|article)\d+$
Match numeric tags ^\d+$
Match tags starting with status- ^status-.*$
